Technical Story

Validate the EditorInterface.yaml of a Content Block package

Acceptance criteria

• The file defines the editor interface of exactly one content block
• At least one field is defined
• The fields are only of types and have only properties defined in the documentation
• The YAML file contents are validated against a JSON schema

Can also be partly done for v2.

TODO: The fields are only of types and have only properties defined in the documentation

-> Conclusion: Since the system ignores not matching types and properties, this is not necessary.

TODO: The YAML file contents are validated against a JSON schema

-> Not clear what to do here and if necessary.
-> Tough to implement and less benefit though
-> Suggestion: omit this or do that later
